How to rotate/flip a texture in Qt3d C++

ademmler

Hi there,

is there a way to flip/rotate a texture in Qt3D. From my code:

auto textureImage = new Qt3DRender::QTextureImage;
    QString fileurl = "file:/path/to file";
    textureImage->setSource(QUrl(fileurl));
    auto planeImage = new Qt3DRender::QTexture2D();    
    planeImage->addTextureImage(textureImage);
auto cylinderMaterial = new Qt3DExtras::QDiffuseSpecularMaterial();
    cylinderMaterial->setTextureScale(1.);
    cylinderMaterial->setDiffuse(QVariant::fromValue(planeImage));

I am looking for something like "textureImage->setRotation" or "textureImage->setTranslation"
or the same for "planeImage" or "cylinderMaterial" ... does it exists ? I could not find this in the documentation.

Otherwise you're probably looking for this:

@kshegunov thx for your hints. Both classes do not offer what I am looking for.

"setMirrored" is half the way. It Would need a "horizontal" or "vertical" option on top.

I am looking for something like:
textureImage->setRotation( 0-380°); or cylinderMaterial->setOrientation( 0-380°);

Either draw the texture rotated with QPaintedTextureImage or generate it rotated beforehand. I see no other way.
